For future aircrafts with flight speed reaching supersonic or hypersonic regimes, hydrocarbon fuel on aboard has to be used as coolant through both significant physical sensible heat and heatadsorbing chemical reactions to meet the challenge of thermal management since aerodynamic heat becomes so large that no structure materials could bear.catalytic cracking of hydrocarbon fuels over zeolite coatings inner cooling microchannels has been highlighted in pervious work as an attractive method of improving cooling capacity of hydrocarbon fuels for the advanced aircrafts.
